Various thin film layers of semiconductor devices may be deposited with atomic layer deposition (ALD) processes. However, some ALD processes produce unwanted byproducts such as ammonium chloride. Some ALD processes are too time-consuming to deposit the desired film. This is oftentimes the case when forming films of silicon carbides and/or nitrogen containing silicon carbides, generally identified as SiC and SiCN, respectively. Some of these approaches employ long dosing times in order to ensure complete reaction of the film precursors on the wafer surface. However, extended dosing times may waste valuable precursor during film nucleation phases. Furthermore, the additive effect of extending processing time may diminish process tool throughput, requiring the installation and maintenance of additional process tools to support a production line. On the other hand, silicon carbide and nitride films produced by conventional approaches foregoing ALD processes may have physical, chemical, or electrical characteristics that provide inadequate device performance. Accordingly, potential improvements in the fabrication of integrated circuitry may be realized through the development of improved methods and apparatuses for depositing SiC and SiCN films, and particular depositing such films through improved ALD type processes.
